The Hebrew calendar is a lunisolar system that synchronizes lunar months with the solar year to keep seasonal holidays aligned. While solar calendars (like the Gregorian calendar) track only the sun, and lunar calendars track only the moon, the Hebrew calendar tracks both simultaneously. This dual tracking prevents spring festivals from drifting into winter over time. 🌙 The Lunar Component: Months
According to the foundational rules outlined on Judaism 101, months match the physical phases of the moon. Duration: Months alternate between 29 and 30 days.
Trigger: Starts precisely with the molad (the calculated new moon). Year Length: Twelve standard lunar months total 354 days. ☀️ The Solar Component: Years
The solar year dictates agricultural seasons, which must align with biblical holiday commands.
